From my previous post, I decided against the DriMaster tool for my portable....even though it has a 16 gallon tank. I saw the new internal jets and after talking with the rep went against it and just went with the duplicate, external jet, that I've been using for many years. It seemed to me that the internal jet would reduce over-spray, but still has the potential to get clogged and therefore a PITA and a time consumer to unclog it.
Honestly, I was rather shocked to hear some of the PSI and water usage numbers that were listed. Makes me wonder if I was using the proper technique. I run at about 75 psi and use only about 1-1.5 gal/ per 2-piece set. But results have been very good as well as dry times.
